Special papermaking machine for efficient production of reconstituted tobacco leaves

Abstract

The invention relates to a paper making machine special for efficient production of reproduced tobacco leaves. The paper making machine comprises an intelligent reproduced tobacco leaf forming device (1), a long net forming device (2), an efficient dehydrating pressing device (3), a reciprocating tunnel drying machine (4), a reproduced tobacco leaf single net ropeless paper leading drier (5), a reproduced tobacco leaf high-coating-rate coating machine (6) and a reproduced tobacco leaf integrated tunnel drier (7), wherein the intelligent reproduced tobacco leaf forming device (1), the long net forming device (2), the efficient dehydrating pressing device (3), the reciprocating tunnel drying machine (4), the reproduced tobacco leaf single net ropeless paper leading drier (5), the reproduced tobacco leaf high-coating-rate coating machine (6) and the reproduced tobacco leaf integrated tunnel drier (7) are sequentially arranged. According to the paper making machine, automation production of the whole processes of putting sheet base pulp on a net, sheet base net portion forming, sheet base pressing and dehydrating, sheet base drying, sheet base coating and drying of the reproduced tobacco leaves is achieved and the paper making machine is high in automation degree and production efficiency, good in equipment operation stability and good in quality of manufactured products.

Description

technical field [0001] The invention belongs to the technical field of a special sheet-making machine for producing reconstituted tobacco leaves by a papermaking method. Background technique [0002] The overall technical level of the current papermaking reconstituted tobacco leaf manufacturing equipment is low, and the degree of automation is low, and many links require manual operations. The sheet base slurry in the papermaking equipment usually adopts an open type headbox with double homogenizing rollers or an air cushion type headbox with double homogenizing rollers. Yankee dryer is usually used for heating and pressing, and the disadvantage is that the surface of the film substrate after hot pressing is tight, smooth, and poor in absorption; the drying method of the film base is usually dried by Yankee dryer and Yankee hood, and the disadvantage is that the papermaking The working speed of reconstituted tobacco production is determined by the diameter of the Yankee cyl...

AI Technical Summary

Problems solved by technology

[0002] In the current papermaking method, the overall technical level of reconstituted tobacco leaf making equipment is low, and the degree of automation is low, and many links need to be manually involved in the operation

The sheet base slurry in the papermaking equipment usually adopts an open type headbox with double homogenizing rollers or an air cushion type headbox with double homogenizing rollers. Yankee dryer is usually used for heating and pressing, and the disadvantage is that the surface of the film substrate after hot pressing is tight, smooth, and poor in absorption; the drying method of the film base is usually dried by Yankee dryer and Yankee hood, and the disadvantage is that the papermaking The working speed of reconstituted tobacco production is determined by the diameter of the Yankee cylinder; the substrate coating adopts roller coating, which has the disadvantages of low coating rate and poor product quality, and the drying of reconstituted tobacco usually adopts single-layer air flotation drying Oven drying, the disadvantage is that the drying section after coating is too long, occupying the space of the site, and the cost of civil construction is high

Due to the insufficiency of each component equipment, the reconstituted tobacco leaf base is poor in online forming quality, the base pressing dehydration efficiency is low, the base drying efficiency is low, the base coating rate is low, the obtained reconstituted tobacco drying efficiency is low, and the working speed of the equipment is difficult. increase, and the device is running unstable
